Uranium 238 the most prevalent isotope in uranium ore has a half life of about billion years; that is half the atoms in any sample will decay in that amount of time Uranium 238 decays by alpha emission into thorium 234 which itself decays by beta emission to protactinium 234 which decays by beta emission to uranium 234 and so on
